To all whom it may concern:

Be it lcnown that l, TVILLIAM T. S. Wennrn, a citizen of the lllnited States, residlng at Yuma, in the county of Yuma and State of Arizona, hare invented new and useful improvements in Combined llrrllsend Untlerrearners, oil which the following is a specification.

The present invention relates in general to drills for drilling Wells and the like, and has reference more particularly to a combined drill and underrearner, l

The primary object of the invention s to provide a structure of the class described which will enable the Well to he drilled and under-reamed to enlarge the hole for the Well casing in one endthe sarne operation.

An apparatus o'l' this lurid has many advantages, for instance, it will enable the drilling apparatus to he operated through the Well casing without reducing the diame ter of the hole.,'thus enabling the operator to keep the casing :lollowing close behind the drill at all. 1, and in this manner exclude surplus Water from the hole and avoid the inconvenience arising when the hole caves in, t ltill another advantage consists in enabling the hole to he drilled at any depth with hutone of easing throughout from top to bottom oi? the hole U The accompanying drawing illustrates one manner oil? reducing the invention to practice lln said drawing, Figure l is a vertical section or a well, illustrating the position the apparatus will assume inthe hole when raised above the hole floor.

- he hereinafter referred to a hole and the hole may be drilled for any purpose, for instance, as an oil well or for the purpose of reaching Water under-ground, As is customary, particularly in drilling oil wells, sections of easing l are used the drilling proceeds, According to the present invcn tion the drilling apparatus will work Within the casing and of course extend below the end of the same to increase thcdepth of the hole. The drilling apparatus particularly the drill isnever of the same diameter as that of the casing. Consequently, it does not produce a hole with a diameter suilicicnt to accommodate the casing. As heretofore practised, the hole, after being made by the drill, is usually reamed out to accoinrnod ate the casing. With the present apparatus the drilling and reaming out of the hole is done in the same operation and by means which are arranged in cooperative relationship to effect such a result in the most convenient and satisfactory manner.

In reducing the invention to practice, it is proposed to, employ a suitable drill, tor instance, an ordinary so-called churn drill will suffice providing it has a tapered top portionfl adapted to have a threaded engagement 4 with the end of the drill rod 5 and with a set screw or the like 6 associated with. this threaded connection for preventing turning of the drill relative to the rod after it .has once been screwed into position. This drill rod 5 extends upwardly and is inclosed by a suitable casing l which snugly fits the same, at the same time ena bling the rod to reciprocate or slide therein,

without undue amountof friction. it sleeve 8 having a threaded engagement on the end of the casing is provided With a pair elf op positely disposed ears 9 made to connect a pair of links 10 through the hing The lower ends of these links are connec by means of a second set of hinges with the under-reams! spades 13. These underreamer spades are constructed with l', tively sharp and outwardly flaring cutting edges 14 and they are urther constructed p with a curvature which will enable them to conform to the contour of the tapering top part 3 of the bit 2.

Consequently, they converge in a direction toward the top of the bit. Thus when the spades are caused to be guided downwardly, they will Ill R. B. WEBER.

RADIATOR.

Specification of Letters latent.

Patented Mar. 22, 1921.

Application filed May 27, 1918. Serial No. 236,790.

To all whom it may concern:

Be it known that I, RALPH B. WEBER a citizen of the United States, residi at a. Charles, in the county of St. Char es and State of Missouri, have invented a new and useful Radiator, of which the following is a s ecification.

he subject of this invention is a radiator intended for use in cooling internal combustion engines and like motors, especially when used oiiautomobiles.

e main object of the invention is the provision of a radiator in which the tubes may be easily removed and replaced.

A still further object of the invention is the provision of means for producing a most efficient circulation of air about the tubes.

The invention also contemplates generally improving the'oonstruction and enhancing the utilit of radiators.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

A practical embodiment of the invention is shown in the accompanying drawings, wherein:-

Figure 1 is a view in front elevation of a radiator constructed in accordance with the invention, a portion being in section;

Fig. 2 is a sectional view on the line 2--2 of F 1g. 1;

Fig. 3 is a detail view in sideelevation of one of the vertical plates or webs;

Fig. 4 is a fragmentary plan view of the to i (plate with the tubes in position therein.

eferring to the drawings by numerals of reference In carrying out the invention there is provided the usual upper radiator tank or receptacle which is composed of the front and rear plates 10 and 11, respectively. The front and rear plates are secured in any suitable manner to a plate 12 which forms the bottom of the top tank or receptacle. A top plate 13, curved or bent to conform to the contour of the upper portion of the radiator, is secured to the upper ed of the front and rear plates 10 and 11 in any suitable manner and held in place thereon the top plate preferably by a strip 13 which is placed along each meetin rear plates and he d in place by screws 15 or otherwise. The ends of the to plate 13 are secured to the ends of the p ate 12 by means of screws 14 orin any ot er suitable manner. A packing (not shown) may be placed between the meeting edges of these plates, if desired, to make a water tight oint. The top plate 13 ma be formed with the usual inlet orifice close by a cap 16.

The radiator is also provided with the usual lower or bottom tank 17 which is in communication with the upper tank through a series of tubes 18 which are threaded into apertures formed in the top of the tank 17 and the upper ends of which are flared outedge of the front and wardly to seat upon the beveled edge. or periphery of the apertures 12 which are formed in the plate 12 for the reception of the tubes. The flared upper ends of the tubes 18 are formed with kerfs or slots 19 for the reception of a screw driver or other tool by which the pipes may be screwed into the top of the lower tank 17.

It will be apparent that the top plate 13 may be easily removed by withdrawing the screws 14 and 15, and a tube 18 removed and replaced without the necessity of removing the radiator from the automobile, and with very little loss of time. Attention is also called to the fact that, though the tubes 18 are herein shown as arranged in regular rows, it is to be understood that they may be staggered, if desired, or arranged in any manner that may be found advantageous and practical.

The upper tank and the lower tank 17 are connected and held in spaced relation to each other by the side plates 20, of the radiator. These side plates are secured to the bottom plate of the upper tank and of the lower tank by means of countersunk screws 21 or in other suitable manner.

Spaced, horizontally arranged plates 22 are connected to the side plates 20 in any desired manner and these plates contain apertures 23, through which the tubes 18 pass with a tight sliding fit.

Inserted in the front of the radiator are the vertically disposed, spaced Webs 24 which have their upper ends connected to the lower plate 12 of the upper tank, and the lower ends of which are connected to the top of the lower tank 17. These connections are made in an 7 circulate properly lower receptacle havin Having thus described the invention, what is claimed as new and sought by Letters Patent, is

In. a radiator the combination with a threaded openings in the top plate thereo of an upper recep-' tacle having tapered seats in the bottom thereof, water tubes insertible downwardly through the bottom of the upper receptacle and having threaded lower ends for engaging the walls of the-threaded openings in the top plate of the bottom receptacle and having enlarged uplper ends adapted to engage the seats in t e bottom of the upper receptacle, there being kerfs in the enlar ed ends of the tubes, and a removable top p ate mounted on theupper receptacle providing access to the enlarged ends of the tubes.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
